My invention relates to improvements in locomotive grease cellars, and has for its primary object a grease cellar in which the end wall is readily removable but is so retained in position that it can not tip outwardly permitting road dust and grit to enter a cellar and intermingle with the grease and thereby cut and score the bearings and locomotive axles.

In the drawings:

Fig. l is an end view of my cellar viewing it from the gate end;

Fig. 2 is a side view of the same;

Fig. 3 is a view similar to'Fig. 1 With the end gate removed;

Fig. 4 is a top plan view of Fig. 3;

Fig. 5 is a vertical section taken on the line 55 of Fig. 1;

Fig. 6 is a face View of the end gate employed; and

Fig. 7 is a top plan view of the same.

In the construction of my device I employ a grease cellar having a body portion which is provided with side walls 8, a bottom 9, and

one end wall 10. Theend wall is cut away arcuately as indicated by the numeral 11 in Fig. 3 so that the cellar can be raised upwardly beneath the axle of locomotive drive wheels.

The forward end 12 of the collar is left upon and is designed to be closed by means of the end gate as will be hereinafter de scribed. I

The cellar is provided with depending lugs or ears 13 which are located at the four corners and below the bottom, and are for the purpose of mounting and securing the cellar in position. The bottom 9 is provided with a depression or recess 14 which receives a spring tending to press a reticulated plate upward against the lower part of the axle. This spring and plate are not shown in the drawings as they form no part of my invention and are at present in common use in grease cellars.

The edges of the walls 8 ad acent the open portion are cut away as indicated by the,

numeral 13 so as to leave a shoulder. In other words this cut away portion is slightly wider than the interior of the cellar. The walls 8 are'also provided at the open end with out wardly projecting lugs 14?. 'These lugs are cut away adjacent the cut away portion 13 as indicated by thenumeral 15 so as to leave a slide substantially L-shaped'in cross section for the edges 16 of the end gate 17. The end gate is also provided with an arcuate cutaway'porti'onsin its upper edge v as-indicated by the numeral 18, whichvserves the same purpose as the cutaway portion 11.. 0

The end gate is provided with outwardly extended lugs 19 which have openings 20. These openings 20 are designed to register with openings 21 formed in the lugs or projections l l" so as to permit the passage ofa cotterkey 22 and when this cotter key is in placeand its end spread, all up and down movement of the end gate isprevented, while the recess portions 15 and 13 prevent any outwardmoveme'nt ofthe end gate even if the cotter key22is not in position. i

The end gate 17 is also rovided with rearwardly extending lugs 23 which fit inside of the lugs 13 at the open end of the cellar.

The cars or lugs 18*, aswe1l as the ears or lugs 23, are provided with openings 24 which'receive cotter keys or bolts for securing the cellarin position beneath the axle. This peculiar type of mounting has not been shown as it is in common practice today and forms no essential part of my invention.

The end gate 17 is placed in position by pushing it upward from the bottom of the cellar and then inserting the cotter keys 22 and also the cotter keys or bolts, which hold the open or farward end of the cellar in the bearing frame.

Bymy construction even should lugs or ears 23 become broken off, still the end gate will be held in position by means of the cotter 90 key 22 and prevent it from droppin down while if the lugs or'projections 19 should become broken ofi', the cotter key 22 will prevent any forward tipping of the end gate as will the slot formed between the lugs 14* and end of the cellar. In other words I have a double protection against the forward tilting of the end gate but at the same time it can be readily removed for repacking the cellar with grease. in

The grease used for this lubrication is what is known as hard grease and is forced into the cellar under pressure and the heat generated by the rotation of the axle softens up a portion of this grease which rises up ward due to its expansion while being softened and furnishes the axle with suflicient lubrication.

It will also be noted that the rearwardly extending lugs 23 limit the upward movement of the end gate so that the movement of the gate is limited both upward, forward and bacK and downward, the forward and back movement being prevented 'bythe lugs 14 which overlap the vertical edges of the end gate and the downward movement by means of :the cotter key 22 as Well as by the :means which pass through the-lugs'23 and 13* when the cellar is secured beneath the ax1e..

Having fully described my invention, what I claim is:

i l. A grease cellar comprising abody portion completely open at its top and one end, a verticallyslidable gate carried by said body portion for closingsaid open end, and perforated lugs carried bythe body portion and gate,said-lu sada pted to receivea fastening means for preventing movement of said gate.

2; A grease cellar comprising a rectangular container entirely open at its top and one end, a removable end gate for closing said open end, lugs substantially 'Lshaped in cross sectionintegral with the side walls of the container and overlying a vportion of the vertical edges of said end gate whereby said gate is vertically slidable, perforated lugs; projecting 'at' right angles from said end gate parallel to and adjacent the first mentioned lugs, and a fastening means extendingthrou h the perforations of said fi'rst and second mentioned lugs for preventing vertical-movement of'said'end gate.

3. A grease cellar comprising a rectangular container-entirely open'at its top and at one end, a vertical slidable end-gate for closing the open end of said container, means carried by the lower end ofsaid gate for limiting its upward movement, means substantially L shaped in cross section carried by said container for preventing outward tilting of said "gate, and means for holding said gate against accidental downward movement.

In testimony whereof I have 'aflixedmy signature. V I p v HARDES P. \VIDDICOMBE.
